We began the day having Music class with Mr. Oliver.
During math, we investigated how to identify a misleading graph as well as identify how a graph can be misleading and understand why some graphs display data in a misleading way.
As a class we investigated 2 different graphs that show the same data.
What do the two graphs show? The average new house prices from 1999-2002
How are the two graphs similar? Both of them are double-bar graphs and both sets of axes represent the same things.
What does the horizontal axis on each graph represent? Time, in years, from 1999-2002 What does the vertical axis on each graph represent? Price, in thousands of dollars
What do you notice about the scale on the vertical axis of each graph? The scale for the graph on the left begins at 100 and is 1 square represents $5000. The scale for the graph on the right begins at 0 and is 1 square represents $25 000.
How are the bars on the graph on the left different from the bars on the graph on the right? On the graph on the right, the bars in each pair are close in height. In the graph on the left, the difference between the heights of each pair of bars is much more obvious.
How are the heights of the bars affected by the scale on the vertical axis? When the scale begins at 1000 and the scale is 1 square represents $5000, the difference in heights of the bars in each pair is much greater than when the scale begins at 0 and the scale is 1 square represents $25 000.
What impressions does the first graph give? The average new house prices in Ottawa are generally much higher than those in Hamilton
What impression does the second graph give? The average new house prices in the two cities are very similar
Who might want to use the first graph? A real estate company in Hamilton, trying to convince people to come to Hamilton to live.
Who might want to use the second graph? A company in Hamilton that is moving its office to Ottawa might use the graph to show its employees that new houses cost about the same in both cities.
Then students were asked what are some things you can do to draw a misleading graph?
I can use a scale that does not begin at 0; I can use inappropriate intervals on the scale of the graph; I can omit some information, such as labels on an axis.
Success criteria:
I can:
-identify a misleading graph
-identify how a graph can be misleading
-understand why some graphs display data in a misleading way
We continued learning more about the Vikings. Some key learning:
- Origins of Vikings (Scandinavia, Norway)
- Viking way of life
- Settlement of Iceland and Greenland
- Sagas
- Success of Viking boatbuilding technology, longboats and sails, navigating without a compass – using stars and environment (type of sea life), etc.
- Vinland
- Important Viking sailors Bjarni Herjolfsson, Eirik the Red, and Leif the Lucky, Thorfinn Karlsefni
- Archeological evidence at L’Anse Meadows in NFL and how this is similar to digs in Greenland
We also discussed how technological advancements allowed travel by sea to be quicker, cheaper, and safer. These advancements included a rudder, latitude & longitude, the caravel, astrolabe, etc. In their table groups, students picked two that they found important and presented this information to the class.
